It’s all part of the equation when you’ve got to fit into that Homelander super suit.

SURE, WHEN ANTONY Starr gets into character as Homelander, the Superman-adjacent sociopathic villain of Prime Video’s The Boys, he’s getting a little bit of help. He wears a muscle-padded supersuit that doesn’t show a whole lot of skin, letting the expertly-crafted garment made by veteran costume designer Laura Jean Shannon do most of the work. But that doesn’t mean he’s slacking when it comes from the superhero prep lifestyle.

In a new episode of Men’s Health‘s “Eat Like,” Starr reveals that he’s got to watch his diet and body closely to maintain his shape for the 7 or 8 months he spends each year filming The Boys—and even at one point was asked to wear a corset to fit into his outfit (which served as some good motivation to lose a couple pounds, he reveals).

While Starr spends much of the “Eat Like” video describing his foods of choice (including his favorite breakfast, proteins, his love for pasta and burgers, and a dairy-filled Homelander cheat meal), he also went out of his way to reveal his personal tip for a really good post-workout protein shake: a tablespoon of peanut butter.

“Just to give it a little bit more texture,” he says. “A little thickness, a little sweetening without being over the top, and also you know you’re getting good healthy fats.”

Starr also revealed some more of of his favorite things. Protein? A nice steak, specifically from New Zealand. Last meal on earth? Bolognese. Or burgers (sometimes he orders three at a time, he says). Or both.
